Don't know if this helps but last year I applied on line for my NoneO visa based on marriage.
It didn't come in time for my flight so I entered on visa exempt, went to my local immigration and extended for 1 month.
Then they said when my visa comes through I can extend for 1 year if I have funds in the bank.
In the mean time me and kids went to Vietnam for a week.
When I came back I activated my NoneO visa for another 3 month. Then extended for 1 year.
If regular people can remember my last year I went for my mouth extention at chainart immigration and they give me a year 😄 I was held up at immigration for ages on my way to Vietnam 😄 I got it sorted
